Biomimetic systems are artificial structures that are inspired by biology. Within bioelectronics, these systems emulate the neural system and are implemented with electronics. An example application is the biosensor.
A biosensor is a device for the detection of an analyte that combines a biological component with a physicochemical detector component. It consists of 3 parts: a sensitive biological element which can be created by biological engineering, a transducer in between which associates both components, and a detector element that works in a physiochemical way.
The most widespread example of a commercial biosensor is the blood glucose biosensor, which uses an enzyme to break blood glucose down. In so doing it transfers an electron to an electrode and this is converted into a measure of blood glucose concentration. The high market demand for such sensors has fueled development of associated sensor technologies.
